around a typewriter platen, five plies l2, 13, M, and I6 being here shown for illustration. Between each of the plies is interposed a carbon paper pack such as ll, only one of which is indicated in Fig. 1, to avoid confusion, but the presence of four of which is indicated in Fig. 2, one less than the number of manifold plies. The carbon packs are commonly all attached to a cradle diagrammatically indicated at [8, which by well-known mechanism not here necessary to be described moves laterally with the manifold pile and also forwardly with the pile as the typewriter carriage and platen are manipulated-and which also may be retracted with respect to the pile and carriage, to the position indicated in dotted lines at liia. The cradle i8 may mount the carbon packs i1 each by a blade l9 whichhas an elongated aperture therein at its outer end for being impaled on a cradle post 2!, a blade with its carbon pack being interleaved between the manifold plies alternatively at opposite sides of the pile, thecradle having a post 2! at each end for this purpose and the blades being thus alternatively right and left. 7

In accordance with the present invention, the apertures 28 and the posts 21 are correspondingly elongated to maintain the blades 19 normal with respect to the lineof movement of the manifold pile toward the platen, indicated by the arrow 22, and--the blade has a slot 23 (Fig. 4) therein, through which the cover flap 243 of the carbon pack carrier 25 is threaded, thus placing the body ofthe blade IS in the bight 26 of the carrier and retaining the blade wellwithin the bight and also preventing the carrier sheet 25 from being accidentally displaced on the blade.

Further in accordance with the present invention, the forward edge of the oarriersheet 25 is adapted to have secured thereto the carbon paper buckle device following the present invention, in-

dicated generally by the numeral 21, and which is illustrated in separated view in Fig. 3. Buckle device 21 in this instance includes a yoke bar 28 which is secured to the forward edge of the carbon carrier sheet 25 as by being passed through the bight portion 29 of the carrier sheet formed by folding this edge of the carrier sheet upon itself as at 3B and securing these edge parts together, preferably the lateral edges of the carrier as by tape 38a, and thus forming a pocket 36b for the carbon paper between the carrier sheet 25 and its folded over edge portion 36. At one end, the yoke bar 28 has a forwardly extending arm 32 in'which is journaled as in a socket or sleeve 32a in the end of the arm, pintle 33 of detent bar 34, which extends alongside the yoke bar 28, and at its other end has a finger-grip or handle 35 projecting beyond the yoke bar 28 for ease of accessibility and manipulation. The pintle 33 is journaled in the arm 32 loosel so that the detent bar may have a swivel or wrist motion as well as a rotary movement withrespect to the yoke bar. One alternative open position of the detent bar is indicated at 3 10: (Fig. 3) and another such alternative position at 3 51) (Fig. 6), for purposes presently explained. The pintle 33 may be upset or swaged slightly as at 35 to hold the detent bar loosely in the socket 32a of the yoke bar arm 32.

At it other end, adjacent the handle 35, the yoke bar 28 carrie a lock member here shown in the form of a clip or hook 251, such as a wire firmly secured to the yoke bar by any suitable means and bent upon itself to provide an open spring loop into which the detent bar may be pressed to hold the detent bar in either one of its alternative locked positions, one of which is shown in Fig. 4 and the other in Fig. 5, as presently more fully explained.

Still further in accordance with the. present invention, the detent bar 34 carries atrammel element or strip '38 which may be provided, as in this instance, by forming a slot'39 in one edge of the detent bar, the trammel strip 38 thus being integral with the detent bar.

In practice the carbon pack includes in addition to the holding means, the usual carbon paper which is desirably in the form of a continuous web til of considerable length, preferably accordion-folded as illustrated, and disposed on the carbon carrier sheet 25 between the latter and its flap 24 so that the transfer side or pigmented face 4! of the carbon is uppermost when an operative length or section of carbon, such as 42, is drawn from the pack for use. It will be understood in the art that by disposingthepigmented face uppermost in the pack, it will come nethermost onthe typewriter platen" between the billhead plies.

Operation of the present novel expedients is as follows: I

A complete carbon packis shown in Fig. 7, including carbon paper and holding means, there being one of these packs between each two contiguous plies of the manifold-pile, the alternate plies and carbon packs being thus superposed one upon another. through the slot 23 of-the'mounting blade and the various right and left packs arranged alternately on the cradle posts between the respective manifold plies, the latter sliding overthe packs during the manifolding operation. It will be understood that the buckle devices 27 are also formed right-hand and left-hand, respectively, corresponding to a blade '19 of each, Figs. 1, 4,

5, 6 and '7 depicting a right-hand pack; Fig. 2

the top fold thereof is drawn out by the operator and passed through the space between the yoke bar 28 and the detent bar 34 of: the buckle device 27. To facilitate thisoperati on, and as shown in Fig. 6, the detent bar Mmaybe-released from the hook 31 and raised-to dispose the carbon thereunder. Next, the carbon paper is threaded through the slot 39 in the detent bar bringing the carbon paper over the trammel strip 38. Thereupon, the detent bar may be temporarily secured to the yoke bar by the hook 31,.as seen inFigAr When the pack is assembled and the buckle device is in position, as seen in Fig. 4, for example, the carbon paper may-be pulled out or fed by the operator to the extent desired (which is usually about as seen in Fig. 7) the carbon paper at this time sliding through the buckle devi'ce. When the desired length of carbon suchas 42 has been drawn out for initial operation, theoperator may then look the carbon paper by. first releasing the detent bar from'the hock3l, and turning the bar over, on'its pintle 33, with respect to the yoke bar 2-8; .This action. buckles or curls the carbon paperupon itself about .the detent in a replicate foldas' seen in'Fig. 5, the trammel strip 38 now- "lyingnext adjacent the yoke bar 28 and having carried; the carbonpaper over with it. To complete;the locking operation, thedetent bar is re-securedtopthe lock member In assembly the flap Z4 is'put or hook 31 (Fig. Any-stresses on the carbon paper tending to draw it from the carbon web 40- are thus prevented from doing so until the operator desires to draw out or feed more carbon. In lieu of temporarily securing the detent baras in Fig. 4 when feedingcarbon, the operator may hold the handle 35 in position with one hand while pullingout the carbon with the other.

Use of thecarbon packs with the parts the position shown in Fig. 5 contemplates forward movement of the carbon, carbon packs and cradle simultaneously with the manifold pile as a billhead is being typed upon, and then retraction of the cradle, carbon packs and carbon paper simultaneously with respect to the manifold pile for the typing of the next bill-head in the continuous pile.

When now a forward length of the carbon becomes worn by use, which may occur as to one or more of the packs and generally as to all of them at the same time, and the operator desires to provide a new forward length, this may be done by tearing off the used carbon, releasing the detent bar of a carbon pack from the position shown in Fig. 5, turning it over upon itself and re-securing it in the position shown in Fig. 4. This at the same time uncurls the carbon paper and permits the latter to slide or feed through the buckle device 21 when pulled out, to the extent desired, the accordion folds of the carbon paper unfolding for this purpose (Fig. 4-) Thereupon the operation is reversed and the detent bar relocked in the position of Fig. 5, which again prevents carbon from being pulled out of the'p ack.

So constructed and arranged, the finger piece or handle 35, together with the detent bar 34, functions as an actuating member for the carbon supply that is accessible at a margin of the manifold pile, and which minimizes the need for the hands of the operator to be inserted between the plies to draw a new length of carbon from the pack; only enough of the hand of the operator need be inserted to get a grip on the paper and pull it forward, the manifold plies being sumciently flexible for this purpose.

Furthermore, since the buckle device 21 is an operative part of the carrier sheet 25 and permanently attached thereto, no loose parts are required which could become misplaced or lost. The pack carrier, typified by the parts 25 and 21, may be sold as a unit to be virtually permanently assembled with, the manifolding mechanism. This merely necessitates replenishment at relatively long intervals of a fresh carbon paper supply, typified as at 49. The user having once purchased the carrier with its associated buckle device, need then only purchasethe accordion folded carbon paper, thus effecting economy in cost of operation of the manifolding unit.

Still further, the buckle device here disclosed provides feeding or metering means whereby any desired length of carbon paper may be drawn friction to movement of the plies with respect to the carbon packs.- Also the flatdetent bar with its flat trammel strip facilitates the-curling or doubling actions on the carbon paper for-holding purposes while avoiding any tendency to tear the paper.

The pocket 3llbadvantageously-holds the body as in Fig. 4, to provide-a new usable length. The

cover flap 24 further assists in maintaining the carbon supplyin position and protects it from tractive influences of the manifold pile.

It will be understood that the term carbon paper is intended to include any pigmented or other transfer sheet, the term typewriter any similar manifolding mechanism, and the'term bill-head any typewritten work.
